FAQs on Oceans Video Lecture - Crash Course for Class 6

1. What are the main features of oceans?

Ans. Oceans are vast bodies of saltwater that cover about 71% of the Earth's surface. They are divided into five major oceans: the Pacific, Atlantic, Indian, Southern, and Arctic Oceans. Key features include their depth, with the average depth being about 12,080 feet, and the presence of marine life, coral reefs, and underwater mountains known as mid-ocean ridges.

2. How do oceans affect the climate?

Ans. Oceans play a crucial role in regulating the Earth's climate. They absorb solar energy and help distribute heat around the planet through currents. This process influences weather patterns, precipitation, and temperature. For instance, warm ocean currents can lead to milder winters in coastal regions, while cold currents can lead to cooler temperatures.

3. What is the importance of oceans for marine life?

Ans. Oceans are essential for marine life as they provide habitats for a diverse range of organisms, including fish, mammals, and plant life. They are crucial for the food chain, oxygen production (through phytoplankton), and biodiversity. Oceans also support fishing industries and recreational activities, which are vital for many economies.

4. What are some major threats to the oceans?

Ans. Oceans face several threats, including pollution from plastic waste, oil spills, and chemicals, which harm marine ecosystems. Overfishing depletes fish populations, while climate change leads to coral bleaching and rising sea levels. These threats can disrupt marine life and impact human communities that rely on oceans for food and livelihood.

5. How do humans utilize oceans?

Ans. Humans utilize oceans for various purposes, including fishing, transportation, tourism, and energy production. Oceans provide food through fishing and aquaculture, serve as trade routes for shipping, and are popular destinations for recreational activities like swimming and diving. Additionally, oceans are a source of renewable energy through wave and tidal power.
